Predicting Substance Use Patterns Among Rural Adults: The Roles of Mothers,Fathers, and Parenthood

This study examined the role of parenthood and parental influences on substance use patterns for 710 stimulant users age 18–61 living in the rural Midwest and Mid‐south U.S. Longitudinal growth analyses showed that a maternal history of drug use was associated with increased baseline drug use severity, lesser declines in severity, and greater plateau of drug use severity over time. Parental conflict was associated with lesser declines in drug use severity, and drug use severity declined more steeply for participants who were themselves parents. Participants with two parents having a history of alcohol use had a greater baseline severity of alcohol use, with paternal history of drug use associated with lower baseline alcohol use severity. These findings demonstrate the importance of identifying parental influences in evaluating adult substance use, and point to the inclusion of parents in efforts to prevent and treat substance use disorders.     

Pro-drug-use myths and competing constructs in the prediction of substance use among youth at continuation high schools: a one-year prospective study

Experimentation with drugs among adolescents often is preceded by faulty beliefs (myths) regarding drug effects. The present study provides empirical demonstration of the utility of a drug use myths index in the prediction of subsequent drug use in a prospective study of substance use among high-risk adolescents. Drug use was measured as an index of recent cigarette, alcohol and marijuana use. A belief-type drug use myths index was compared as a predictor of drug use with four other frequently researched correlates of drug use. The other measures were of social influence, outcome expectancies, attitudes toward wrongness of drug use and sensation seeking. The belief-type drug use myths, attitudes toward wrongness and sensation seeking indices were found to be significant predictors of drug use among our sample of 1074 youth when controlling for gender, ethnicity and prior drug use. These findings have implications for understanding factors contributing to individual differences in drug use behaviors and could benefit the development of drug education programs for high-risk individuals.     

School Substance Use Norms and Racial Composition Moderate Parental and Peer Influences on Adolescent Substance Use

Parental and peer influences on adolescent substance use have been well demonstrated. However, limited research has examined how parental and peer influences vary across school contexts. This study used a multilevel approach to examine the effects of school substance use norms and school racial composition in predicting adolescent substance use (a composite measure of alcohol, tobacco, and marijuana use) and in moderating parental and peer influences on adolescent substance use. A total of 14,346 adolescents from 34 schools in a mid‐western county completed surveys electronically at school. Analyses were conducted using hierarchical linear modeling. Results indicated that school‐level disapproval against substance use and percentage of minority students at school were negatively associated with adolescent substance use. School‐level disapproval moderated the association between peer substance use and adolescent substance use, with the association being stronger when school‐level disapproval was lower. School racial composition moderated the influence of parental disapproval and peer substance use on adolescent substance use. Specifically, both the association between parental disapproval and adolescent substance use and the association between peer substance use and adolescent substance use were weaker for adolescents who attended schools with higher percentages of minority students. Findings highlighted the importance of considering the role of school contexts, in conjunction with parental and peer influences, in understanding adolescent substance use.

An 8-year study of multiple influences on drug use and drug use consequences

Multiple long-term influences on young adult drug use and abuse were tested within an interactionist perspective using latent-variable causal models. Intrapersonal influences included early drug use and social conformity. Proximal interpersonal influences were captured by perceived peer drug use, perceived adult drug use, and family disruption. More distal influences included perceptions of community approval or disapproval for drug use. Outcome measures included not only use of drugs but also disruptive drug use (getting high at work or school) and self-admitted problems with drugs. Data were obtained from 654 participants at three equally spaced time points during an 8-year longitudinal study that began when the subjects were in junior high school. Confirmatory factor analyses were used to test the adequacy of the hypothesized measurement model. Subsequently, a structural equation, or path model, was used to examine the across-time relations among the latent and manifest variables. Stability effects were found for all repeatedly measured latent variables across the 4-year spans. Social conformity strongly influenced other latent variables across time. Early drug use and perceived adult drug use were prominent predictors of young adult drug use, whereas prior drug use predicted disruptive drug use and a lack of social conformity predicted problems with drug use. Early adult alcohol use predicted later disruptive drug use and problems with drug use. Perceived adult drug use generally influenced later alcohol use, whereas peer drug use influenced later cannabis and hard-drug use. Implications for prevention and treatment using a multicausal interactionist perspective are discussed.     

Religiosity and adolescent marijuana use

Among adolescents, religiosity has been associated with lower rates of marijuana use, though few studies have examined its impact on the perceived risk of use. There is strong support that perceived risk of using marijuana is negatively correlated with the frequency of use. We examined the relationship among religiosity, perceived risk, and marijuana use from a national survey of adolescents that contained questions about lifetime, weekly, and past month substance use, social support, religious involvement and attitudes, and perceived riskiness of use. We tested a structural equation model of relationships among latent variables of religiosity and perceived risk, and an observed variable of total days of marijuana use in the past 12 months. Results indicated the model was a good fit to the data and described a mediating relationship of perceived risk of use between religiosity and marijuana use. Implications for leveraging religiosity in prevention of substance use are discussed.     

大学生网络使用与网络利他行为:网络使用自我效能和性别的作用

感觉寻求、同伴压力对高中生烟酒使用的影响

对来自山东日照市两所普通高中1~3年级的689名学生进行问卷调查,考察感觉寻求、同伴压力（包括烟酒使用同伴压力与其他同伴压力）对高中生烟酒使用的影响,以及同伴压力的调节作用。结果表明：（1）感觉寻求、烟酒使用同伴压力对高中生烟酒使用有正向预测作用,其他同伴压力也能显著预测其饮酒行为。（2）烟酒共用同伴压力调节感觉寻求和高中生烟酒共用间的关系,只有在高烟酒共用同伴压力下感觉寻求才会显著预测烟酒共用;饮酒同伴压力也调节感觉寻求和高中生饮酒间的关系,只有在高饮酒同伴压力下高感觉寻求者才会有较多饮酒行为;其他同伴压力无此调节作用。（3）吸烟同伴压力不能调节感觉寻求和高中生吸烟间的关系。     

Substance Use and Health and Safety among Homeless Youth

This study examines how substance use is associated with the health and safety of homeless youth using cross-sectional, self-report data from 285 homeless adolescents. Path models were used to examine concurrent relationships between youth’s substance use and multiple aspects of their health and safety, including measures of psychological distress, housing risk and instability, and medical problems. Substance use was examined with both global (i.e., a composite of days of use across various drugs and alcohol) and specific (i.e., rates of use of specific drugs, injection drug use) measures. After controlling for demographic and historical variables, number of days of use was significantly related to psychological distress, whereas injection drug use was significantly related to housing risk. Examination of specific drugs revealed relationships between psychological distress and the use of alcohol, cocaine, and amphetamines, and a specific relationship between housing risk and the use of heroin. None of the measures of substance use was significantly related to youth’s medical problems. Implications for interventions with homeless adolescents are discussed.     

The influence of self-efficacy on alcohol use among American Indians

The influence of self-efficacy (general and substance use) on alcohol use among 114 American Indian and Native Alaskan adults was examined. Analysis of variance was performed to assess differences between alcohol use groups (nonuse, low use, and medium-high use). Low general self-efficacy (GSE) was associated with higher alcohol use. High substance use self-efficacy (SSE) was associated with higher alcohol use. Moreover, low GSE was associated with higher SSE. Results indicate that alcohol use may be in response to feelings of powerlessness within one's life and may be sustained by perceived feelings of control over use. The study suggests that the concept of self-efficacy appears to relate to empowerment issues and, as such, would have important applications for use with minority individuals.     

Minority adolescents and substance use risk/protective factors: a focus on inhalant use

Despite the fact that inhalant use is a growing problem among youth in the United States, relatively little attention has been paid to the demographic and social factors related to its use. This study used data from a household survey of adolescents in Washington state, and found that race/ethnicity was a strong predictor of lifetime prevalence of inhalant use, with Native-American youth being particularly likely to use inhalants. Comparing the age at initiation of inhalant use to other legal and illegal substances, we found that cigarettes and inhalants showed the lowest age at initiation. We conducted logistic regressions on lifetime prevalence of inhalant use, and compared these models to other substances. In general, we found that attachment to parents. parents' drug use, and school attachment were strong predictors of lifetime use of marijuana, alcohol, and inhalants. However, while peer drug use was a strong predictor of marijuana and alcohol use, it was not a significant predictor of adolescents' use of inhalants. Our final set of analyses included inhalant use in regression models predicting other problem behaviors: these analyses demonstrated that inhalant use was a strong predictor of involvement in problem behavior.     

感知易用性会影响网络游戏中虚拟商品的使用意愿么?——感知有用性和玩家神经质的作用

Strengths use and work engagement: a weekly diary study

The present study among 65 civil engineers investigates the impact of organizational support for strengths use on weekly work engagement and proactive behaviour. Positive psychology postulates that strengths use makes people feel authentic and efficacious. We argue that employees use these positive psychological states as resources that fuel work engagement and proactive work behaviour. Participants completed a general questionnaire regarding strengths use support, and a weekly quantitative diary questionnaire regarding their strengths use, self-efficacy, work engagement, and proactive behaviour over a period of five consecutive workweeks. In line with the hypotheses, the results of multilevel structural equation analyses showed that organizational strengths use support was positively related to weekly strengths use. Furthermore, the results indicated that weekly strengths use was positively related to weekly work engagement and proactive behaviour, through weekly self-efficacy (sequential mediation). Although strengths use support contributed indirectly to work engagement (mediated by strengths use and self-efficacy), there was no significant indirect relationship with proactive behaviour. Our study indicates that strengths use is associated with employees’ levels of self-efficacy, work engagement, and proactive behaviour and that organizations can help employees to use their strengths more often by giving them the opportunity to do what they are good at.     

Adolescent Substance Use: Preliminary Examinations of School and Neighborhood Context

In considering the influences of microsystems on adolescent substance use, familial and peer contexts have received the most extensive attention in the research literature. School and neighborhood settings, however, are other developmental contexts that may exert specific influences on adolescent substance use. In many instances, school settings are organized to provide educational services to students who share similar educational abilities and behavioral repertoires. The resulting segregation of students into these settings may result in different school norms for substance use. Similarly, neighborhood resources, including models for substance use and drug sales involvement, may play an important role in adolescent substance use. We briefly review literature examining contextual influences on adolescent substance use, and present results from two preliminary studies examining the contribution of school and neighborhood context to adolescent substance use. In the first investigation, we examine the impact of familial, peer, and school contexts on adolescent substance use. Respondents were 283 students (ages 13 to 18) from regular and special education classrooms in six schools. Although peer and parental contexts were important predictors of substance use, school norms for drug use accounted for variance in adolescent use beyond that explained by peer and parental norms. Data from a second study of 114 adolescents (mean age = 15) examines neighborhood contributions to adolescent substance use. In this sample, neighborhood indices did not contribute to our understanding of adolescent substance use. Implications for prevention are presented.     

Predicting 13-year-olds' drinking using parents' self-reported alcohol use and restrictiveness compared with offspring's perception

This study examined whether offspring's perception of parental frequency of alcohol use and restrictiveness towards offspring's alcohol use could be used as a substitute for parental self-reports. Offspring's perception were compared with parents' self-reported alcohol use and restrictiveness in ability to predict offspring's own alcohol use. Respondents were 924 offspring, 642 fathers and 729 mothers. Correlations between fathers' and mothers' self-reported frequency of drinking alcohol and offspring's reports of parental frequency of drinking alcohol ranged from 0.55 to 0.70. Fathers' and mothers' self-reported alccohl use and restrictiveness explained less than two per cent of the variance in their offspring's alcohol use in regression analyses, while offspring's perception of parental drinking frequency and restrictiveness exaplained about eight per cent of the variance in offspring's alcohol use. These results represent a challenge to studies of young adolescents which interpret offspring's reports of parents' alcohol use as a surrogate measure 'of parents' self-reported alcohol use.     

Implications of MDMA use for prospective memory function and substance use patterns in an Australian sample: A web‐based pilot study

The use of amphetamine type stimulants, particularly MDMA, is a global concern. Little research has been conducted on the association between MDMA use and everyday memory function—prospective memory. Twenty‐five MDMA users, 37 cannabis users, and 43 illicit substance‐naïve controls were assessed on their substance use history and reported prospective memory performance as measured by the Prospective Memory Questionnaire (PMQ) using a web‐based survey. There were significant differences between MDMA users and controls and cannabis users and controls on long‐term episodic subscale of the PMQ. However, given the high prevalence of cannabis co‐use by MDMA users, it was not possible to determine if MDMA use alone is associated with prospective memory performance. The substance use patterns of the sample were evaluated. Alcohol was the most used substance followed by tobacco, cannabis, and MDMA. The incidence of polydrug use was high, with all illicit substance use reporting having used at least two substances in their lifetime. The present study supports previous research into prospective memory deficits associated with substance use, and provides a basis for future research, particularly for elucidation of prospective memory deficits specific to MDMA use and further evaluation of substance use patterns.

Methamphetamine use in a rural college population: associations with marijuana use, sensitivity to punishment, and sensitivity to reward

This study examined predictors of methamphetamine use in a 6-month prospective study of 2,270 rural young adults. Sensitivity to punishment (SP), sensitivity to reward (SR), and gender were exogenous variables in an observed variable path analysis with 3 endogenous criteria: Time 1 (T1) marijuana use and methamphetamine use at T1 and Time 2 (T2). SP was negatively associated with marijuana use at T1, and this association was attenuated by SR. Male gender was positively associated with marijuana use. T1 marijuana use and SR were positively, and male gender negatively, associated with T1 methamphetamine use. T1 methamphetamine use, T1 marijuana use, and SP were positively associated with T2 methamphetamine use. Methamphetamine use prevalence and the role of distal predictors and proximal indicators of drug involvement are discussed.     

Posttraumatic Stress Symptom Clusters,Trauma History,and Substance Use among College Students

Previous research found associations between experiencing specific posttraumatic stress disorder (PTSD) symptom clusters and use of specific substances among combat veterans, women exposed to domestic violence, and an inpatient sample; however, research has not utilized a college sample when considering this association. This study assessed trauma history, PTSD symptoms, alcohol use, and nonexperimental use of depressants, stimulants, opioids, cannabinoids, hallucinogens, inhalants, and steroids in college students. Results indicate unique associations between the PTSD symptom cluster of reexperiencing and use of depressants, avoidance/numbing with use of depressants and opiates, and hyperarousal with use of opiates. Further, the individual subclusters of behavioral avoidance and emotional numbing were associated with use of depressants and avoidance was associated with hallucinogen use. Implications are discussed.     

Do Smarter People Employ Better Decision Strategies? The Influence of Intelligence on Adaptive Use of the Recognition Heuristic

Within the adaptive toolbox approach, it has repeatedly been shown that, on average, people tend to adapt their decision strategies to the decision context. Building upon these results, we investigated whether individuals systematically differ in their ability to successfully adapt to the situation when applying the fast‐and‐frugal recognition heuristic (RH). In decisions between recognized and unrecognized choice objects, individuals can base their choices solely on recognition, as predicted by the RH, or they can use further knowledge retrieved from memory. Since intelligence has been conceived as the ability to successfully adapt to different situations, we expected intelligence to influence the degree of adaptive use of the RH. To test this hypothesis, we first re‐analyzed data that referred to a decision domain for which RH‐use is known to perform well. As expected, individual RH‐use increased with general intelligence. Next, we designed an experiment addressing individual RH‐use in two new decision domains, one domain for which RH‐use was less effective than knowledge‐use and another domain for which both strategies were about equally effective. In addition, we tested whether fluid or crystallized intelligence best predicts adaptive use of the RH. RH‐use was found to decrease with fluid but not crystallized intelligence when RH‐use was less effective than use of further knowledge. In contrast, there was no significant association between either type of intelligence and RH‐use when none of the two strategies was optimal. We conclude that adaptive use versus non‐use of the RH is moderated by fluid intelligence. Copyright © 2017 John Wiley & Sons, Ltd.
